This weed has been popping up randomly everywhere in my garden beds for a few years now. If not pulled out right away, it will quickly grow into a tall tree, with woody stem and well-established roots. Does anyone know what this plant is? I live in Houston, TX.
The attached picture is one of the larger weeds. They can get much bigger. The leaf pattern is basically always the same as the picture. I have never seen anything else notable about them, such as flowers, or seeds but then again I'm a lazy gardener and not very observant.
